Add Go 1.24.x to CI test matrix

Adds Go 1.24.x to the CI test matrix alongside existing 1.22.x and 1.21.x.
This ensures gopy works with the latest Go version.

Based on go-python#378 by @coffeemakingtoaster.

Note: Two tests remain skipped due to known Go 1.21+ CGO issues
(see go-python#370). This is expected.
